If we compare Zalman Reserator 1 Plus with any air cooling system or some traditional type of water cooling system with a fan on top of the heatsink, then the Zalman baby is undoubtedly better from the noise prospective. The totally silent cooling solution is always better than any whisperingly quiet fans.
As for the cooling efficiency, Zalman Reserator 1 Plus also did a great job in our test session. It managed to cope easily with an Intel Prescott processor overclocked to 4GHz and a powerful GeForce 6800 GT based graphics card. The temperatures of both: CPU and GPU were lower than in case we used a Zalman CNPS7000B-Cu working at full speed and a standard graphics card cooling system.
If we compare Zalman Reserator 1 Plus with the previous model, Zalman Reserator 1, the biggest difference will certainly be the use of new water units. The CPU water unit proved highly efficient. It is not only as good the old water unit modification, but it also better suits to withstand corrosion, is smaller, lighter and easier to mount.
The current water unit for the graphics processor is a way better than the “thing” they used to offer with the previous Reserator model. Although, there is still room for improvement. I believe that if they use copper footing and bigger ribbed grid inside the unit will make the device much more efficient. Nevertheless, even now this water unit guarantees lower GPU temperature than the standard graphics card cooling system.
Other innovations introduced in Zalman Reserator 1 Plus are not vital but pleasing: black color of the radiator, protective additives for the water solution, new connecting pipes for the tubes, special back panel bracket for the system case, etc.
All in all, the new Reserator 1 Plus has definitely turned out better than the previous model.
